Towards A Unified Soil Mechanics Theory demonstrates mathematical models for saturated and unsaturated soils by defining the effective stress equation. Chapters present hydraulic models that simulate water distribution in pores. Parameters from these models are then used to demonstrate the use of an effective stress equation to understand the mechanics of soils that have different material constitutions.
Towards A Unified Soil Mechanics Theory paves the way for a universal theory of soil mechanics that has a wide range of applications. The book is a valuable reference to civil engineers, geotechnical engineers, earth scientists and hydrologists interested in soil mechanics at both academic and professional levels.
Key Features
- Sequentially explains soil modeling techniques for easy understanding
- Demonstrates the use of an effective stress equation based on data from porous-solid models.
- Explains how porous-solid models can simulate the soilwater retention curves of materials.
- Establishes an elastoplastic framework for the volumetric behavior of unsaturated soils that is used to simulate the phenomenon of collapse upon wetting and the behavior of expansive soils.
- Explains the practical application of fully a coupled hydro-mechanical (critical state) soil model
- Includes scientific references for further reading
